Overview
Debian package that adds QEMU microvm machine type to the Proxmox UI. microvm VMs boot in under 200 ms, use only virtio-mmio, and give full KVM isolation. Uninstall restores original files.
How it works
Patches two qemu-server files to add microvm as a selectable machine type. A standard Proxmox VM emulates a full x86 PC with PCI bus and BIOS, but a microvm skips all that — direct kernel load, virtio-mmio only, much smaller attack surface. The result is KVM-grade isolation at LXC-comparable boot times. Currently the only Proxmox integration for QEMU microvm.
Features
Under 200 ms boot
No emulated PCI, no BIOS. Direct kernel load.
Full KVM isolation
Own kernel per VM. No shared kernel.
Proxmox UI
Appears as a machine type option. Managed like any VM.
Fully reversible
dpkg -r restores original qemu-server files.
